This invention relates to certain new and useful improvements in window sash constructions, and has for its primary object to provide vertically sliding window sashes capable of being horizontally swung into the room of a building by either a hinged move ment or movements completely moving the sashes from the window frame to facilitate cleaning the window panes and eliminating the necessity of a person sitting or standing upon an outside window sill or ledge while cleaning windows.

Another object of the invention is to provide a window sash construction of the above type having the usual sash weights associated with the sashes with laterally shiftable guide strips or stiles with which crank members are associated for holding the stiles in their forward operative positions to be engaged by the sides of the window sashes and being laterally shiftable to permit side sliding movement of the window sash to free one edge thereof from the window frame for permitting movement of the window sash into a room for purposes of cleaning the window panes.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing 2- Figure 1 is a horizontal sectional view of a window sash construction showing the laterally shiftable guide stiles for the window sashes held in operative position by a crank shaft;

Figure 2 is a horizontal sectional view, similar to Figure 1 showing the crank shaft rotatably shifted with the guide stiles laterally moved to permit sidewise movement of the window sashes with the latter partially removed from the window frame;

Figure 3 is a fragmentary front elevational View of the window construction show-.

ing the key ends of a pair of crank shafts controlling positions of the guide stiles at the lower end of the window rame; and

Figure 4 is a perspective view of one of the key operated crank shafts.

Referring in detail to the accompanying drawin which shows the preferred embodiment of the inventiomthe reference numeral 1 indicates a window frame having lower and upper sashes 2 and 3 respectively vertically slidable therein, separated by the vertical parting strips 4 and retained in the frame 1 by the molding strips 5. Thesides of the window frame 1 are provided with the usual vertical channels orpockets 6 in which the sash weights 7 travel that have cord and pulley connections with the sashes 2. and 3.

-At each side of the parting strip.4there are disposed guide stiles8. and 9, the guide stiles 8 being rigidly positioned and forming a closure for one side of the pocket 6 while the guide stiles 9at the other sideof the window frame which form a closure for the adjacent pocket. 6 are shiftably mounted horizontallyof the window frame. Means is provided for retaining the shiftable guide stiles 9 in their operative position with respect to the window sash and comprises a crank shaftlO journaled at its ends in the side walls of the window frame to extend through the pocket 6. The crank arm-:11 of the crank shaft 10 is disposed in the pocket 6 and when in the position shown in Figure 1 is engaged with the guide stiles 9 tohold them laterally projected intooperative position with respectto the window sash. The shiftable guide stiles 9 are associated with the lower section of the window frame and both the lower and upper sashes must be completely lowered to permit removal thereof .as later described from the window frame, the

stiles at one side of thewindow frame being rigidly mounted the entire height of the frame while the opposite sideof the window frame has the lower sections of thestiles shiftable and upper sections rigid.

As shown in Figures 3? and 4, one end of the crank shaft 10 extendsthrough the inner side of one frame and has a key receiving socket 10a in its exposed end, it being ob-, served that two controlling crank shafts are associated with the two shiftable stiles 9 and are mounted in the window frameat points adjacent the lower sash.

ripper and lower ends of the and said crank shafts each having one end ssuming that the shiftable projecting through the window frame to restiles 9 are in their locked position as shown ceive an operating key.

in Figure 1 and it is desired to swing either the upper or lower sash into the room for purposes of cleaning the same, the crank shaftslt) are rotated by a suitable device associated. with the key ends 100 to be moved to the position shown in Figure 2 With the crank shafts so disposed, the sash may be laterally moved for displacing or laterally moving the adjacent stile 9 a distance until the stile moves into abutting engagement with the adjacent end of the crankshaft and to free the opposite side edge of the sash from confinement by the,v molding strip 5, whereupon, the sash may be: swung out of the window frame and into a room to permit access to both sides of the same for purposes of cleaning the window pane. When it is desired to remove the upper sash from the window frame, the same is lowered to be aligned. with the'shiftable' stile .9- and the same may be removed from the frameand be disposed adjacent the removed lower sash, or the lower sash-.may' be raised to the upper end of the window frame when the ripper sash is lowered to be removed. The sash weights balance the sashes when they are removed from the frame the sashes may rest upon the Window sill during the cleaning operation; The sashes'aremoved into the frame and aligned with the: .stilesafter the cleaning operation and uponv working the crank shafts 10,. the shiftable stiles 9 are moved and being engaged with. the sashes also move them to their retained positions confined bythe molding strips 5.-

Fromthe above detailed descriptionof the.

invention, it isbelievedthat: the construction and operation thereof will at once he apparent, and while there is herein shown and described a preferred embodiment of the invention, it is nevertheless to beunderstood that minor changes may be made therein without departing from. the spirit and scope of the invention as claimed.

In a window sash construction, a window frame, "sashes; vertically slidable therein, stationary parting strips for the sashes, guide stiles-for opposite side edges of the sashes, the stilesat one: side-of the window 'alined with the lower sash being: laterally shiftable to permit side sliding movement of the sash to free the-oppositeedge of the sash from the retaining moldingstrip for removal from the frame, a pair of crank shafts. journalled through the: window frame adjacent the upper and, lower ends of the shiftablie stiles having the crank portions thereof movable toward and away from the stiles for controlling' shifting movement thereof, the hearing ends of the crank shaft providing move: ment limiting stops for the shiftable: stiles In testimony whereof I aflix my signature.
